1. Problem Description
We are given a graph of a function and asked to find the intervals where the function is increasing, decreasing, or constant, as well as the domain and range of the function.
2. Solution Steps
* Increasing Interval: The function is increasing when the y-value increases as the x-value increases. From the graph, this occurs from to . At the function has a hole, so the interval is .
* Decreasing Interval: The function is decreasing when the y-value decreases as the x-value increases. From the graph, this occurs from to . Since is a closed circle, the interval includes . Therefore, the interval is .
* Constant Interval: The function is constant when the y-value remains the same as the x-value increases. From the graph, this occurs from to . Therefore, the interval is .
* Domain: The domain is the set of all possible x-values for the function. From the graph, the function is defined from to . Since is a closed circle and is an open circle (hole), the domain is .
* Range: The range is the set of all possible y-values for the function. The minimum y-value is , and the maximum y-value approaches
1. Therefore, the range is $[-2, 1)$.
3. Final Answer
* Increasing:
* Decreasing:
* Constant:
* Domain:
* Range:
